bug 13085 allows for a single component such as alpha to be set for a whole
image,
this related bug proposes that each component can be independently set.
in data visualisations, where the canvas is large and most pixels need to be
changed at high refresh rates, component arrays can be large to sort, and set.
Allowing a single components to be set per pixel may provide considerable
advantage. see peepo.com for demonstration.
there are also significant advantages to colour separation, when presenting
data.
and furthermore, there are accessibility implications for people not requiring
full colour images, and those using mobile phones, or slower processors.
